黄土高原小流域景观虚拟现实技术研究与应用

Research and Application of Landscapes Virtual Reality Technology to Small Watershed

以“数字地球”为指导思想,通过三维地形模型构建、纹理映射和实时动态立体显示等技术开发了小流域虚拟现实景观,其真实感强、地表信息丰富、精度高、动态性强、可视化程度高。探讨了小流域景观虚拟现实技术在水土保持中的应用。

Guided by digital earth and based on 3D terrain model construction, and using orthophoto map texture mapping and real time dynamic stereo showing technology, small watershed virtual reality landscapes are researched and developed. Small watershed virtual reality landscapes have high substations, plentiful terrain information, high accuracy, and are easily depicted audio-visually for dynamic observation. The applications of landscapes virtual reality technology to small watersheds are discussed.
